The National Institute of Standards and Technology (NIST) has released a very interesting (but long!) document (click HERE to download) that explains cloud computing technology in plain terminology. At 84 pages and 1.9Mb, it is not a brief document but is extremely comprehensive and should give anyone a thorough understanding of the issues involved if they are contemplating a move into this area.
The document is currently in draft form. If you wish to make a comment to NIST, you may do so up to 13th June 2011 with an email to email@example.com.
